-PointerHolder to std::shared_ptr
-================================
-
-To perform update:
-
-Cherry-pick pointerholder branch commit
-
-Upgrade just the library. This is not necessary, but it's an added
-check that the compatibility code works since it will show that tests,
-examples, and CLI will work properly with the upgraded APIs, which
-provides some assurance that other people will have a smooth time with
-their code.

-Remove all references to PointerHolder.hh from everything except

-
-make check -- everything passes
-
-Increase to POINTERHOLDER_TRANSITION=4
-
-Do a clean build and make check -- everything passes
-
-Final steps:
-
-* Change to POINTERHOLDER_TRANSITION=4
-* Check code formatting
-* std::shared_ptr<Members> m can be replaced with
-  std::shared_ptr<Members> m_ph and Members* m if performance is critical
-* Could try Members indirection with Members* for QPDFObjectHandle
-
-When done:
-
-* Update the smart-pointers section of the manual in design.rst
-* Update comments in PointerHolder.hh
